CURTAIN-FIXTURE.

Specification of Letters Patent.

Patented Dec. 3, 1907,

Application filed June 294 1905. Serial N0- 267.4:80i'

To all whom it may concern:

Be it known that I, PAUL A. I-IOUGHTAL- live, a citizen of the United States, residing in Riverton, New Jersey, have invented certain Improvements in Curtain-Fixtures, of which the following is a specification.

My invention relates to an improved device for frictionally holding a shade or ourtain in a given position against the tendency of its spring roller to raise or roll it up, and more particularly has to do with that type of curtain holding structure in which the lower portion of the curtain is provided with frictionally acting devices, held by means of outwardly pressing springs, in engagement with the bottoms of the window frame grooves in which the curtain operates.

The object of the invention is to provide a relatively simple and inexpensive structure applicable to the lower portion of a curtain, which shall automatically operate to hold said curtain in any given position against its tendency to move upwardly under the action of the spring curtain roller. This object I attain as hereinafter set forth, reference being had to the accompanying drawing.

This figure is a vertical section illustrating my invention as applied to a curtain rod of the well known form.

In carrying out my invention I provide the well known curtain rod, commonly placed in the lower portion of a curtain, with heads or boxes in which are mounted rollers or wheels placed to bear upon the bottoms of the grooves of a window frame. These rollers are so mounted that they are free to bodily move up or down relatively to the head or shoe by which they are carried, and this latter is provided with some form of retarding device or brake placed to act upon said rollers to prevent their revolution when the heads or boxes are .moved upwardly through a small distance, as under the action of the spring curtain roller.

In the above drawing, A represents a tubular curtain rod, in each end of which is carried a spring-actuated bar B having mounted upon its outer end the head or box O. Rollers c are mounted in this box; it being provided with hearing pins or spindles c journaled in elongated slots 0 formed in the sides of the box.

In one form of my invention, flat springs c are held to the box by screws and extend into the same so as to be engaged by the surfaces of the rollers when these move to the lower ends of the slots 0 If, under operating conditions, the curtain, with its rod and boxes, is moved to some desired position in a Window frame and is then released, the

' spring curtain roller immediately tends to,

and, in fact. does move the curtain rod and the heads 0, carried thereby, upwardly.

Such upward movement, however, imme diately causes the rollers c to move from the positions shown in Fig. 1, to the opposite ends of their respective slots 0 and thereby come into engagement with the springs 0 Said rollers are thus wedged between said springs and the bottom of the window frame groove (indicated at D), with the result that further revolution of the rollers under the action of the spring curtain roller, and consequently further motion of the curtain rod and curtain, is effectually prevented. It is still possible, however, to move the curtain either up or down by hand.

It will be noted that as soon as the curtain rod is moved downwardly, as by hand, the roller is immediately released from its braking or frictional holding device, while. if the curtain be moved upwardly by hand, it is necessary to exercise a greater force than that available from the curtain spring roller, which is not sufficient to overcome the holding force due to the jamming or wedging of the rollers 0 between their braking structures and the bottoms of the window frame grooves.

It will be noted that it is not essential to provide a spring to actuate the head carrying bars B, since the above described actions will take place even if the said bars be immovably fixed to the curtain rod.

I claim as my invention:

1. A holding attachment for a curtain consisting of a curtain rod, heads carried thereby, a bodily movable roller and a spring piece carried by each head, said spring pieces being inclined to the lines of movement of the heads and placed to retard revolution of their respective rollers when these are in definite positions, substantially as described.

2. A holding attachment for curtains consisting of a curtain rod, a holding head on each end thereof having elongated slots in its sides, a roller for engaging a window-frame groove, said roller having a spindle mounted in the slots, and a spring structure carried by each head extendlng outwardly from the a back thereof and terminating at a distance In testimony Whereof, I have signed my from the bottom of the Window-frame groove name to this specification, in the presence of less than the diameter of the roller, said structWo subscribing Witnesses.
